# This is a reusable helper component containing various i18n related
24
# utilities. It also helps narrow the gap between GTK and KDE frontends
25
# to a given application, by providing the translate_widget function to
26
# translate both language and GTK accelerators and styles to QT widgets.
27
# I hope to see this improve and grow into an abstract dual-gui helper
28
# framework, to make it much easier to port Ubuntu/GTK apps to Kubuntu
29
# as well as maintain them as they grow.
